SPECIFICATION forming part of Letters Patent No. 542,661, dated July 16,1895. 4 Application filed July l'7J 1894. Serial No. 517,824- l (N0model-l To rif/ZZ whom, it may con/cern.-

Be it known that I, ROBERT HERMANN THIELEMANN, a subject of the Kin g ofSaxony, and a resident of Lichtenstein, in the Kingdom of Saxony, GermanEmpire, have invented certain new and useful Improvements in Furniture,of which the following is a full, clear, andV exact description.

The present invention consists of a device in connection with tables,desks, and the like,

' by means of which the feet and legs of the occupant may be kept warm.

It is Well known that many people whose vocation necessitates theirsitting at a desk or table for the greater part of the day sulfer fromcold feet during Winter, a fact which besides personal discomfortgenerates also a number of diseases. The disadvantage is 0bviated bymeans of the present invention, which comprises a combined table ordesk,

stool or chair, and device for warming the feet and legs arrangedunderneath the said table or desk before the stool or chair in themanner hereinafter more particularly described; and in order to makethis specification more easily intelligible reference is had to theaccompanying drawings, in which similar letters denote similar partsthroughout the several views.

Figure l is a side elevation of the device; Fig. 2, a horizontal sectionon the line a. b, Fig. 1; Fig. 3, a vertical cross-section through thedesk; Fig. 4, a plan of the desk-slab; Fig. 5, a detail side elevationof the mechanism Y for adjusting the position of the desk-slab;

Fig. 6, a plan of Fig. o with the retaining springs for the slab inposition in the rails thereof; Fig. 7, a similar plan showing the saidsprings disengaged. i

The device consists of the outer structure D, advantageously in the formof a desk having an interior lining of zinc Z and anintermediate layerof felt F. Within the shell G, which is open at the front part Where theoccupant is intended to sit, is a second casing of zinc Z', both shelland casing being covered in by a top plate or covering C. The interiorcasing Z has covering ot' cane R, woven in the usual manner andstretched in a metallic frame R', corresponding in shape and size tothev interior conguration of the said casing. The side of this interiorcasing,

against which the chair T is situated, only extends from the base-plateup to the seat ot' the chair, so that the two casings Z and Z inclose anintermediate space having the plan form of three sides of a square, Fig.2, the said space being closed in on the chair side by the strips T3 T3.Thus the occupant' of the chair can sit on the same with his feet 6o andlegs extending into and resting on the i tioor of the interior of thecasing Z', direct contact with the zinc walls being prevented by thecane-covering R.

Within the space between the bottoms of the exterior and interiorcasings Z Z a ring of steam-distributing nozzles K, having a steamsupplypipe D, lead upward and through the top covering C to a stop-valve A andthen outward, Fig. 1, in any convenient direction. 7o Thus asteam-jacket is formed around the chamber -in which the occupant of thechair has his legs. Upon the top plate C and cornmunicating with theinterior of the steamjacket is a safety-valve S, While in the baseplatea valve V is arranged, having a protecting-cap Eand operated by means ofany suitable lever system St, Figs. l, 2, and 3, by a button or handlearranged on the top of the plate C. A thermometer This arranged upon 8othe latter plate by which to control the temperature ot' thesteam-jacket. The valve V is for letting oft the condensed Water fromthe steam-jacket, and when employed the cap E should lirst be removed.

On an extension T of the base-plate the chair T is arranged, havingfolding seat T2 adapted to fold onto the back ot' the chair so as tofacilitate getting into position before the desk. The valves and otherdevices on 9o the plate or covering C are covered by the slab of thedesk P which is advantageously made adjustable and arranged in thefollowing manner: On suitable upwardly-extending arms or brackets tif ofthe plate C or upper 95 part of the casing G, Figs. -l and 5, are fixedhorizontally-extending arms if', Fig. 5, carrying guide rolls r r, Figs.6 and 7, in grooves, of which rshaped rails s s are mounted to run, saidrails being supported at theiriorn.0 ward ends on rolls s3, mounted onarms s?, supported on the plate C. The Writing plate or slab P is hingedat its forward ends at cc to two rails s s,which latter have theirI endshereinafter described. At therear side of the plate-'L'. e., the sidefarthest from the writer two graduated sector-bars m are pivoted to theunder side of the said plate P at Z, said sectors being each adapted toslide in slots of thecorresponding rail s, so that the slat can betilted and supported at any desired angle in the substructure G by meansof the setscrews n of the said rails s, which clamp the said sector-barsin any position. The slab P can further be slid backward from theoccupant, as shown in dotted lilies in Fig. 1, and is arrested in itsforward or normal position by means of the following device: To the armsif', Figs. 5, 6, and 7, are fixed fiat springs f,-

carrying at their free ends studs a, adapted when the slab is in itsnormal positien,to engage in orifices or slots e of theupwardlyextending web of the rails s s. Suitably guided on the web ofthe said rails is a wedge shaped sliding block g, attached by aconnecting line or rod to one end of a pivoted lever 7c pivotedv to theunder side of the slab I). The inclined surface of this slideblock gisadapted when drawn forward by moving the lever /c into the positionshownin Fig. 7 to contact with the pin or stud z ofthe springf, and pushthe same back out of the slot e of the rail so that the slab P can thenbe pushed backward away from the occupant into the position shown indotted lines in Fig. l. On releasing lthe lever 7c the block g willreturn to its original position under the pull of its spring t'. Thus,inorder to push the slab back to facilitate getting into position beforethe desk or table, it is only necessary to pull back the levers 7c andpush the slab y out, its outward movement being determined tom of whicha s'titfening-ring I, having feet resting on the base-plate is providedto prevent treading through the zinc lining.

Th e

slab may then be drawn forward and the temperature within thesteam-jacket regulated as desired. If deemed necessary, buttons H H maybe arranged on the plate C for the reception of a covering for theknees.

Instead of steam heating any other suitable heating may be employed,although the former is advantageous.

By means of this apparatus the feet and legs of persons sitting at thedesk will beheld continually warm.

I claim as my invention- 1. A desk or table, having an outer shell orsubstructure, an' inner chamber within said exterior shell to receivethe occupants legs and feet, a covering plate common to both shell andinterior casing an adjustable slab mounted on and above said cover meansto adjust the same and means for heating the space inclosed between thesaid shell and interior casing substantially as described.

2. A desk or table having an exteriorshell and an interior chamber, acover common to both an adjustable slab mounted on said cover, a steamdistrbuter between the shell bottom and inner easing bottom, steamsupply pipe to said distributer, means for regulating the steam supplyand a condensed water cock arranged in the bottom of the exterior shellsubstantially as described.

3. A desk or tabfe, having an outer shell or substructure, an innerchamber within said exterior shell, a covering plate common to bothshell and interior casing means for heating the space between said shelland interior casing, an adjustable slab, sliding rails hinged to saidslab, fixed guide rolls to said rails and means for arresting said railsin their forward or normal position, sector bars hinged to said slab,and guided in slots in the rail ends and means for clamping said sectorsin any position substantially as described..

In witness whereof I have hereunto set my hand in the presence of twosubscribing witlleSSeS.
